Connection to the internal modem is made via the RJ-11 jack, or two captured wire connectors, located on the right side of the meter. Connect the meter to the telephone network with an FCC Part 68 compliant telephone cord (that has two male RJ-11 plugs).

If you have the captured wire connector option, connect the meter to the telephone system with the (bare wire to RJ-11) cable provided. If you have the CTR-21 compliant internal modem option, you may also require an adaptor to interface with your regional telephone jack.
